The RAVPower Luster External Battery Pack is a 6000 mAh USB charger with 2.1 amps of power that includes the handy coiled USB cable and a carry pouch. The RAVPower Luster has enough power to charge a smartphone or other mobile device several times with enough amperage to charge higher draw devices like the iPad.

The RAVPower Luster is about 3.67 by 1.61 by .85 inches and has the power button on one side while the connections are on the end. The micro USB connection is for charging your devices while the male USB connection is for charging the external battery pack.

The RAVPower Luster also has an LED light on the end for help in finding your way in the dark that turns on and off using the power button. To charge your devices you simply connect them to the male USB connection and press the power button but you do have to remember to press the power button.

You do need to power the pack on in order to charge your devices and you can use the four blue LED lights under the silver band to tell how much power the pack has. The four blue led lights are not very bright and in full sunlight may be a bit difficult to see but it works well enough for an indicator.

The LED lights do give you some idea of the charge of the external battery pack and the 6000 mAh charge can last for a really long time. According to RAVPower the 6000 mAh Luster will run your iPhone for 15 hours plus 40 hours of extra talk time and an additional 150 hours of music play.

The Luster External Battery Pack also has short circuit, overload and over current protection for a safer device as well as a handy one. I have had the RAVPower Luster for a month and had no problems charging my numerous mobile devices including a Samsung smartphone, Nexus 7 tablet and my BlackBerry Playbook.

The only thing I had any concern with was remembering to press the power button to start charging my device which is common on some of the external battery packs. The RAVPower External Battery Pack is a great pack that has plenty of power to charge your mobile devices several times and is handy in a compact size.

The RAVPower Luster comes in four colors, costs about $30 and is available from Amazon, Newegg and other websites as well as RAVPower. I highly recommend the RAVPower Luster 6000 mAh as a powerful external battery pack that works well and is a very handy size for pocket or briefcase.

The RAVPower WiFi Disk is a handy little device no larger than a 2.5 inch hard drive that powers smartphones or tablets as well as transfers data wirelessly. You can not only transfer files between devices and computers but also use the WiFi Disk as a hotspot and a network file server.

The RAVPower WiFi Disk charges mobile devices with its internal 3000 mAh battery and allows you to save or copy files from an SD or Mini SD Card in the SC Card slot. The RAVPower WiFi Disk has a power button and reset button along with indicators and a USB connection to connect a hard drive to it.

The WiFi Disk comes with a USB to micro USB cable and an instruction book that will come in handy for connecting and setting up your network and WiFi connection. You charge devices just by plugging them into the USB connection while you can charge the WiFi Disk using the micro USB connection.

Using the device as a hotspot for other devices like a phone or tablet to connect to the internet is easy and does not take long to set up. You can use the WiFi Disk easily to transfer data to and from an SD card or from a connected hard drive that plugs into the USB connection.

The WiFi Disk is compatible with both android and iOS devices so you can use it to easily transfer from a MAC PC or Apple tablets and Windows or Android devices. To use an Android or Apple device like smartphones you need to use an app which is available from iTunes or Google Play.

The AirStor app I have been using with my Nexus 7 works very well and I have had no problems moving files and images from my tablets and smartphone to my computers. I can easily use an SD card and takes pictures with my DSLR camera and then right on the spot upload them to my tablet using the WiFi Disk.

Other uses like streaming videos works most of the time but for longer videos you may not want to go wireless as there is just too much data in large video files. I tried watching a full length movie and a few times during playback it would skip but for shorter videos it works just fine.

Transferring files and streaming as well as using the disk for a hotspot to connect multiple devices all worked just fine and I had no problems with the WiFi Disk other than what to try next. To connect the WiFi Disk to an internet network you simply pair your device whether it’s a smartphone or tablet to it and use the app to connect the WiFi disk to the network.

You then have free reign to connect the tablet or smartphone to the internet or use the WiFi Disk as a storage or transfer device between your devices. Being able to connect a hard drive to the WiFi Disk while also charging it makes a great time saver as I could easily see working on files and wanting to keep the disk topped off.

I had no problems using the WiFi Disk and can easily recommend it as a way to connect devices wirelessly and transfer files as well as charge them. I highly recommend the RAVPower WiFi Disk as a great portable charger and network adapter to transfer files and connect to the internet.
